Mathematical Physics 1
A.Y. 2020/2021
Learning objectives
The aim of the course is the illustration of the Lagrangian (and Hamiltonian, time permitting) formulation of the Newtonian mechanics. Qualitative analysis of the differential equations will be exploited, and
fundamental questions like stability, variational principles and Kepler's
problem will be considered.

Assessment methods and Criteria
The final examination consists of two parts: a written exam and an oral exam.
- During the written exam, the student must solve some exercises in the format of open-ended and/or short answer questions, with the aim of assessing the student's ability to solve problems in Lagrangian mechanics. The duration of the written exam will be proportional to the number of exercises assigned, also taking into account the nature and complexity of the exercises themselves (however, the duration will not exceed three hours). In place of a single written exam given during the first examination session, the student may choose instead to take 2 midterm exams. The outcomes of these tests will be available in the SIFA service through the UNIMIA portal.
- The oral exam can be taken only if the written component has been successfully passed. In the oral exam, the student will be required to illustrate ideas, techniques, definitions and results presented during the course and will be possibly required to solve problems regarding Lagrangian mechnics in order to evaluate her/his knowledge and comprehension of the arguments covered as well as the capacity to apply them.
The complete final examination is passed if all two parts (written, oral) are successfully passed. Final marks are given using the numerical range 0-30, and will be communicated immediately after the oral examination.
